Shadow of the Tomb Raider in September?

Shadow of the Tomb Raider is apparently coming in September. The
Tomb Raider Website has a caption
that says MARCH 15TH, 2018 6:00 A M P D T, presumably a tease of an
announcement (which thankfully dispenses with a countdown timer to challenge our
math skills). It seems we won't have to wait until tomorrow to learn the
significance of this, though, as
Kotaku snooped through the HTML and found a release date listing. They say
the site's source code includes the following tidbit: ""Shadow of The Tomb
Raider is the climatic finale of Lara’s origin story. Available September 14th
2018."
